I am trying to obtain information about my great grandmother (Margaret Purcell Carroll). She came to Boston, MA in the late 1800's. She was the second wife of Maurice Carroll (following the death of his first wife). Maurice is buried in Donneraile, Cork, Ireland. Possibly someone descended from Maurice's first wife would know something. There was a branch of this family in Medford, MA. where they owned Carroll's Diner.
